Since so much of the Earth is covered in ocean, almost two thirds of the Earth’s surface is covered with oceanic crust. Continental crust is on average older, more silica-rich and thicker than oceanic crust. The oldest parts of the continental crust include some rocks that are nearly 4 billion years old. New continental crust is still being ...

A tide is a special type of wave that is perceived as the vertical movement of ocean waters. Tides are caused by the gravitational pull of the moon and sun. Although the moon is very small compared to the sun, it is much closer to Earth. As a result, its influence on ocean tides is more than twice that of the sun.

How much does it eat? Planet Earth: Ocean Deep – Answer Key. What is the largest fish in the ocean? How large is it? Whale Shark; 30 tons 12 meters. Why do the small pilot fish follow the white tip shark? The shark can sense food better than the fish and they can eat the little bits left by the shark.

About how much of Earth is covered by clouds at any one time? What is the ratio of water than falls on land as compared to the amount that falls onto the oceans? As you watch the animations, watch the direction that the wind is blowing in.

A continuous range of mountains called the mid-ocean ridge winds around Earth. There are mountains on the abyssal plain, too. Some reach above the ocean surface to form volcanic islands. Others, called seamounts, are completely under water.

A ship disappears from view on the ocean horizon because the Earth is round. Water always maintains a horizontal orientation regardless of the elevation of the two land masses it is between. If you were flying a plane along Earth’s equator in the exact opposite direction as the spin of the Earth but at the same speed, the sun would remain at ...

Then continue pouring “ocean” water until you get to 970 ml (almost to 1000). Students are often very surprised that the oceans hold that much of the Earth’s water. You can then use a dropper to show them how much is in the other 6 reservoirs listed on the table. Put up the overhead of actual percentages of reservoirs of the water cycle.

As a result of interacting with the material in this webquest, students will learn how much water on Earth is actually freshwater, how we will use satellite technology to explore Earth’s water cycle and measure global precipitation, why gaining that information is important to civilization, how water moves through Earth’s water cycle, the ...

Although abyssal plains are the flattest features on Earth, they are not completely so. Extinct volcanoes, or seamounts, sometimes rise as much as 1 km above the surrounding plain and occasionally break the surface to form islands, as at Bermuda. The most striking landforms of the ocean floor are the mid-ocean ridges and deep-sea trenches.

The Pacific Ocean covers 64 million square miles (165 million square kilometers). It is more than two times the size of the Atlantic. It has an average depth of 2.4 miles (3.9 kilometers). 40. Why is Earth mostly crater-free compared to the pockmarked Moon? Earth is more active, in terms of both geology and weather.

The Earth's climate is different from what it was only 20,000 years ago when ice sheets covered much of the Northern Hemisphere. Since the industrial revolution humans have been dumping exhaust from burning fossil fuels into the atmosphere, thereby significantly increasing the amount of carbon dioxide (CO2) in the atmosphere.

How do the earth’s rotation and the ocean’s temperature affect the whirling motion of a hurricane? The rotation causes the rising air to turn, and the warm ocean adds a steady fuel of moist air. This results in strong spiraling winds. Why is a hygrometer an important weather instrument?
